Application filed June 7, 1906. Serial No. 320,661.

To all whom it may concern:

Be it known that 1, CHARLES F. EDsoN, a citizen of the United States, residing at Los Angeles, county discovered a new and useful Improvement in Intermitting Apparatus for Cooling Cars, Warehouses, and the Like; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements. in intermitting apparatus for cooling cars, Warehouses and the like; and the objects of my improvement are, first, to construct means for reducing the temperature of the atmosphere in warehouses and compartments where perishable articles are kept, and other articles stored that may be damaged by continued high temperatures; and second, to provide an apparatus for'cooling cars in which fruits and other articles of food are shipped long distances in hot climates and at seasons of the year when the weather is warm. I

The invention consists essentially in the construction, combinationand arrangementof the several parts, as will be hereinafter fully described in the specification shown upon the drawings and specifically pointed out in the claims made a part hereof. I attain these objects by the construction, combination and arrangement of the several parts illustrated in the accomoperating the valves in the pipes.

panying drawings, in which- Figure 1. is a view partly in elevation and partly in' section of a car, parts thereof broken away, showing boxes stored in the car, illustrated in full lines and in dotted lines, andportions of the apparatus at the station of the Warehouse for cooling the car after being loaded shown in dotted lines; Fig.2. is an end view in elevation of the car and fiortion of the platform of the warehouse; parts-of the apparatus for reducing the temperature of the car shown in full and dotted lines; Fig. 3. is a perspective view, on an enlarged scale of a portion of one of'the pipes of my improved apparatus and devices secured thereon for conveniently ascertaining and regulating the temperature of the air within the pipe; Fig. 4is a perspective view on an enlarged scale of a section of one of the pipes of my apparatus having a thermometer removably fastened within the pipe for conveniently ascertaining and regulating the temperature of the air within the pipe; Fig. 5 is a top plan View of a car shown in full line and a portion of the apparatus illustrated in full and dotted line and parts thereof broken away; Fig. 6 is a view in elevation of the cold coil box'or generator for cold air, portions of the pipe connected therewith and levers for drawings, is loaded with boxes 2, and 2, of fruit or other perishable articles it is desirable that thewarm or hot air in the car surrounding the boxes be exhausted therefrom and the car before being started on its journey to market, be filled with cold air and with this end in view, the'car doors are tightly closed and the valves 20, and 21, shown upon Figs. 5 & 6 of the drawings, are shut down and the exhaust or suction operation of the fan 22, put in operation in order to remove the hot air from the central, storage compartment 1, and it is carried out of the car through the opening 1.0, in the partition 10 into the tank or compartment 5, thence through the pipe 11, into pipe 12, into pipe 13, thence into pipe 14, into the outer air. The construction of the fan 22, shown upon 'Figs. 2, and 5, of the drawings is not necessary to be illustrated; it is employed to exhaust the hot air from the said compartment 1, or to force the cold air from the cold air generator 6, into the said storage compartment.

The fan 22, is driven by means of the belt 16, passing over the pulley 17, upon the shaft 15, the said belt being connected to the pulley on a motor shaft not required to be shown. The said fan 22, is constructed to ex haust the impure, hot air from the compartment 1, of

the car through the pipes 11, and 12, as hereinbefore described, and after this has been accomplished, to force or blow the cold air from the cold coil box or cold air generator or conduit 6, into the opposte end of the car through the pipe 7, the said valves 20, andZ] being simultaneously opened by grasping the long lever 30,

at 31, as hereinafter more fully described, which at the same time closes or shuts down the valve 23, in the pipe 14. The said long lever 30, is fulcrumed upon the fork 32, of the standard or post 33, secured to the side of the cold coil box or cold air generator or conduit 6, as shown upon Fig. 6 of the drawings. The opposite end of said long lever 30, has secured thereto at 34, the forked link 35, and to the lower end of said forked link 35, the swiveled link 36, is connected and the opposite end of said link 36, is swiveled to the valve 20. To the r opposite end of the said long lever 30, hear the point 3] thereon I swivel the long link 37, and to the lower end of said long link 37, is swiveled at one end the short link 38, and the opposite end thereof is movably connected to the valve 23.

The shorter lever 40 is fulcrumed to the fork 41 oi the post 42, secured to the top of the cold coil box or cold air generatoror conduit 6 near one end thereof, and the longer end 43 of the said lever40 is swiveled to the leverlink 44 at one end and the opposite end' of said leverlink is movably connected to the double-ended-forkedlink 45 and to the said link is connected the valve 21 by means oi the link 46. The shorter end of the said shorter lever 40 is movably connected to the double-ended-forked-link 51 at one end, and the opposite end thereof is lnovably connected to the long lever 30, as shown in Fig. 6 of the drawings.

It will readily appear that when theoperator grasps the long lever 30, at the point 31, as hereinabove stated, and elevates that end of said long lever 30, that the valve 23, will be opened, the valve 20, closed and the valve 21, will also be closed. All the impure air hereinbefore referred to, contained in the closed, loaded car, will by the suction and exhaust operation of the fan 22, be iorced into the outer air through the pipe 14. The loaded car now being purified by removing theair accumulated therein while the fruits in the boxes were being stored therein, the operator again grasping the long lever 30, at the point '31, thereon, ieverses and depresses the said long lever 30, by pla ing the same in the position shown in full lines upon Fig. 6, closing the valve 23, within the pipe 14, opens the .valves 20, and 21, and the blowing operation of the fan 22, forces the cold air which remained undisturbed in the coldcoil. box or cold air generator 6, while the car was being emptied of foul air contained therein, now blows the cold air from the said box or generator 6, through the pipe 7, into the tanks or compartments 4, and 4, thence through the opening 8, 8, in the partition 8, and into the storage compartment 1, of the car upon the boxes 7 2, therein, against the battle plate 9, and downward around the boxes 2, the openings 10, and 10, in the partition 10", being closed by the pivoted covers 10 This operation is continued until the thermometers 25, in the pipes 7, and 11, indicates that the temperature of the air in the car has been reduced to the desired point tor preserving the perishable fruits or other articles contained in the boxes 2, and 2, of the compart ment 1, of the can The pipes 7 connecting the cold air generator with the tanks 4, 4, the central storage compartment 1, the two-end tanks 5 5, the pipe 11, connecting one of the said tanks 5 with the fan 22, and

the pipe 13, leading from the fan to the cold air generator 6, form an endless chamber or conduit.

What I do claim as my invention and desire to seblower and the chamber, and being adapted to control the passage through the conduit, a second valve adapted to control the opening to the atmosphere, and means connecting said valves whereby they may be intermittently and simultaneously operated, and a coil in the conduit.
